Security that respects your privacy by design
Q Swiss Security GmbH exists to give organisations and individuals a level of digital protection that does not trade away their privacy. We believe security and privacy are not opposites — they are the same promise. Every system we build is engineered so that we cannot see your data, log your activity, or expose your metadata, even if we wanted to.
- Independent, Swiss-governed engineering
- Privacy is a design requirement, not an afterthought
- Transparent, auditable security architecture
The foundations of everything we build
Five non-negotiable principles guide every product and service we deliver.
Zero Metadata
We design systems that minimise and, wherever possible, eliminate metadata — the hidden data about your data that can reveal more than the content itself.
Zero Logs
No activity logs, no session trails, no behavioural records. What you do stays with you — we keep no record that could be subpoenaed or leaked.
PQC-Resistant Encryption
Our cryptography is hardened against quantum computers, using post-quantum algorithms so your data stays secure far into the future.
End-to-End Encryption (E2EE)
Data is encrypted on your device and only decrypted by the intended recipient. We never hold the keys — and we never could.
Blockchain-Based Security
We leverage distributed ledger technology for tamper-evident integrity and verifiable, auditable security guarantees.
DSG / GDPR compliant by design
As a Swiss company we operate under the Federal Act on Data Protection (DSG / nFADP) and align our practices with the EU General Data Protection Regulation (GDPR). Our zero-metadata, zero-log architecture is the strongest possible foundation for data-protection compliance.
